Volume of a cylinder = \pi r^{2} h
r = \frac{D}{2}
  = \frac{8.4cm}{2}
  = 4.2cm

h = 14.5cm
\pi = 3.14

V= (3.14) * ((4.2cm)^{2})*  14.5cm
  = 803.1 cm^{3}

How to determine the speed of light.
LuckyWell [14K]

Answer:

Hey mate....

Explanation:

This is ur answer....

<em>By adjusting the path length while observing the interference pattern and carefully measuring the change in path length, the wavelength of the light (λ) can be determined. The speed of light is then calculated using the equation c = λf.</em>

Hope it helps!

What is the density if<br> a sample of rock has a mass of 69<br> g and a volume of<br> 23<br> ml?
kiruha [24]
Density = mass / volume

= 69g / 23 ml

= 3 g / ml.

Thus, the density of the sample is 3 grams per ml or 3g/ ml

When you assume that the gas is behaving ideally, the gas molecules are very far from each other that they do not have any intermolecular forces. If it behaves this way, you can assume the ideal gas equation:

PV = nRT, where

P is the pressure
V is the volume
n is the number of moles
R is a gas constant
T is the absolute temperature

When the process goes under constant pressure (and assuming same number of moles),

P/nR = T/V = constant, therefore,

T₁/V₁=T₂/V₂

If V₂ = V₁(1+0.8) = 1.8V₁, then,

T₂/T₁ = 1.8V₁/V₁

Cancelling V₁,

T₂/300=1.8
T₂ =540 K

If you do not assume ideal gas, you use the compressibility factor, z. The gas equation would now become

PV =znRT

However, we cannot solve this because we don't know the value of z₁ and z₂. There will be more unknowns than given so we won't be able to solve the problem. But definitely, the compressibility factor method is more accurate because it does not assume ideality.
